Definitions
- the present disclosure relates to a vehicle rear structure.
- JP 2007-99031 A describes a towing hitch member.
- a hitch member main body provided on the vehicle rear side and extending in the vehicle width direction is fixed to a vehicle body via a first connecting member, a second connecting member, and a third connecting member. More specifically, the first connecting member is fixed to a rear side member, the second connecting member is fixed to a side member outer, and the third connecting member is fixed to a lower back panel.
- a load input into the hitch member main body at the time of towing using the towing hitch member is dispersedly transmitted to the rear side member, the side member outer, and the lower back panel.
- the hitch member main body is fixed to the vehicle body via the first connecting member, the second connecting member, and the third connecting member. This accordingly increases the number of components, thereby causing an increase in weight and cost. Accordingly, it is desirable to reduce the number of connecting members.
- a connecting member to a rear side member as a vehicle frame member.
- the load is transmitted to the rear side member via the connecting member.
- a rotational moment that displaces an inner portion of the rear side member in the vehicle width direction to downward in the vehicle up-down direction around the rear side member is applied to a vehicle body.
- a tensile force that acts outward in the vehicle width direction is applied to the lower end of a lower back panel.
- the rear end of a floor pan molded by deep draw forming is joined to the lower back panel so as to form a housing portion for a spare tire, and it is necessary to provide a flange for joining to the lower back panel in the rear end of the floor pan.
- the rear end of the deep drawing portion of the floor pan has to be offset in the vehicle front-rear direction with respect to the rear ends of other parts of the floor pan at the time of molding. This also requires that a part of the lower back panel is offset in the vehicle front-rear direction so as to correspond to the part thus offset.
- the lower back panel when a tensile force is applied to the lower end of the lower back panel, the lower back panel might greatly deform such that the part offset in the vehicle front-rear direction in the lower back panel is extended. On this account, a large stress might be generated in a welding-spot portion where the lower back panel is joined to the floor pan. In this regard, there is still room for improvement in the related art.
- the present disclosure restrains weight and cost and also restrains a stress to be applied to a welding-spot portion between a lower back panel and a rear floor pan at the time when a load is input from a towing hitch member.
- An aspect of the present disclosure is related to a vehicle rear structure.
- the vehicle rear structure includes a projection portion and a lower back panel joined to a rear end of a rear floor pan provided in a vehicle rear portion and rear ends of a pair of rear side members. Each of the rear side members is attached to a corresponding one of two ends of the rear floor pan in a vehicle width direction.
- the lower back panel has: a through-hole into which a connecting member of a towing hitch member is able to be inserted, the towing hitch member being attached to the rear side members; a first offset portion formed inwardly in the vehicle width direction from the rear side members and offset toward an offset side, the offset side being one side in a vehicle front-rear direction; an inclined wall portion formed inwardly in the vehicle width direction compared with a corresponding one of the rear side members, the inclined wall portion being configured to connect the first offset portion to a general part, the general part being a part other than the first offset portion and the inclined wall portion in the lower back panel; and a welding-spot portion provided in the inclined wall portion, the welding-spot portion being welded to a part of the rear end of the rear floor pan.
- the projection portion is provided between the welding-spot portion and a joining portion of the lower back panel. The projection portion projects towards the offset side.
- the joining portion is a part where the lower back panel is joined to one of the rear side members.
- the first offset portion may be offset toward the offset side so as to correspond to a second offset portion which is offset toward the offset side.
- the second offset portion may be a part of the rear end of the rear floor pan, which is offset toward the offset side.
- the lower back panel is joined to the rear end of the rear floor pan provided in the vehicle rear portion and the rear ends of the right and left rear side members each attached to a corresponding one of the two ends of the rear floor pan in the vehicle width direction.
- the lower back panel includes: the through-holes into which the connecting members of the towing hitch member to be attached to the rear side members are insertable; the offset portion formed inwardly in the vehicle width direction from the rear side members so as to be offset toward one side in the vehicle front-rear direction in the rear end of the rear floor pan; and the inclined wall portion formed inwardly in the vehicle width direction from a corresponding one of the rear side members so as to connect the offset portion to a part other than the offset portion.
- the offset portion projects in the same direction as a part of the rear end of the rear floor pan, the part being offset toward the one side in the vehicle front-rear direction. Further, the inclined wall portion is provided with the welding-spot portion to which the rear end of the rear floor pan is partially welded.
- the offset portion When the lower back panel is extended by the tensile force, the offset portion is displaced to the opposite side from the offset direction and a part other than the offset portion is displaced toward the offset direction, so that a stress concentrates on the welding-spot portion in the inclined wall portion.
- the projection portion projecting in the same direction as the offset portion is provided between the welding-spot portion and the joining portion joined to the rear side member in the lower back panel of the present disclosure. Accordingly, when the tensile force is applied to the lower back panel, the projection portion is extended by the tensile force thus applied and displaced toward the opposite side from the projecting direction, that is, toward the opposite side from the offset direction, so that the displacement of the part other than the offset portion toward the offset direction is generally canceled.
- weight and cost of the vehicle structure can be restrained and a stress applied to the welding-spot portion between the lower back panel and the rear floor pan at the time when a load is input from the towing hitch member can be also restrained.
- the projection portion may be provided at a position including a part of a lower edge of the lower back panel.
- the projection portion is provided at a position including a part of the lower edge of the lower back panel. That is, the projection portion is provided in the lower edge of the lower back panel on which the tensile force directed outwardly in the vehicle width direction acts most when a load directed downwardly in the vehicle up-down direction is input into the towing hitch member from an object to be towed.
- a stress toward the offset direction concentrates more on the welding-spot portion in the inclined wall portion near the lower edge of the lower back panel in comparison with a part other than the welding-spot portion, but it is possible to more surely reduce the stress directed toward the offset direction and applied to the welding-spot portion near the lower edge of the lower back panel due to the displacement of the projection portion provided at the position including a part of the lower edge of the lower back panel.
- a stress applied to the welding-spot portion between the lower back panel and the rear floor pan at the time when a load is input from the towing hitch member can be further restrained.
- the projection portion may have a generally trapezoidal shape increased in width toward a lower side in a vehicle up-down direction.
- a lower end of the projection portion may be placed to be lower than the joining portion in the vehicle up-down direction.
- the projection portion has a generally trapezoidal shape increased in width toward the lower side in the vehicle up-down direction in a vehicle rear view, and the lower end of the projection portion is formed to include a region which is lower than the joining portion between the lower back panel and the rear side member in the vehicle up-down direction. That is, the upper end of the projection portion is placed between the welding-spot portion of the inclined wall portion and the joining portion joined to the rear side member in the lower back panel and the lower end of the projection portion is formed to include the region which is lower than the joining portion joined to the rear side member in the vehicle up-down direction, thereby making it possible to increase a region where the projection portion is formed.
- the stress applied to the welding-spot portion between the lower back panel and the rear floor pan at the time when a load is input from the towing hitch member can be restrained in a wide range.

- Each of the connecting members 58 is attached to a corresponding one of the two ends of the hitch member main body 56 in the vehicle width direction.
- the connecting member 58 is formed generally in a rectangular plate shape with the longitudinal direction being along the vehicle front-rear direction and the plate-thickness direction being along the vehicle width direction, and projects toward the front side in the vehicle front-rear direction from the corresponding one of the two ends of the hitch member main body 56 in the vehicle width direction. Further, as illustrated in FIG. 8 , the connecting member 58 is inserted into the through-hole 48 (see FIG.
- the towing hitch member 54 is configured so as not to be directly fixed to the lower back panel 16 .
- the lower back panel 16 is attached to the rear end of the rear floor pan 14 provided in the vehicle rear portion and to the rear ends of the right and left rear side members 18 each attached to a corresponding one of the two ends of the rear floor pan 14 in the vehicle width direction.
- the lower back panel 16 includes: the through-holes 48 into which the connecting members 58 of the towing hitch member 54 attached to respective rear ends of the rear side members 18 are insertable; the offset portion 40 formed inwardly in the vehicle width direction compared with the rear side members 18 so as to be offset toward one side in the vehicle front-rear direction in the rear end of the rear floor pan 14 ; and the inclined wall portions 42 formed inwardly in the vehicle width direction compared with the rear side members 18 so as to connect the offset portion 40 to the general surfaces 38 as the parts other than the offset portion 40 .

- the inclined wall portions 42 are provided with the welding-spot portions 44 to which the rear end of the rear floor pan 14 is partially welded.
- the projection portion 50 projecting in the same direction as the offset portion 40 is provided between the welding-spot portion 44 and the joining portion 46 to which the rear side member 18 is joined in the lower back panel 16 in the present embodiment. Accordingly, when the tensile force T is applied to the lower back panel 16 , the projection portion 50 is extended by the tensile force T thus applied and is displaced toward the opposite side of the projecting direction, that is, toward the opposite side of the offset direction (see the alternate long and two short dashes line in the figure), so that the displacement of the part other than the offset portion 40 toward the offset direction is generally canceled.
- the projection portion 50 is provided at a position including a part of the lower edge of the lower back panel 16 . That is, the projection portion 50 is provided in the lower edge of the lower back panel 16 on which the tensile force T directed outwardly in the vehicle width direction acts most when a load directed downwardly in the vehicle up-down direction is input into the towing hitch member 54 from an object to be towed.
- the stress toward the offset direction concentrates more on the welding-spot portion 44 in the inclined wall portion 42 near the lower edge of the lower back panel 16 in comparison with the part other than the welding-spot portion 44 , but it is possible to more surely reduce the stress directed toward the offset direction and applied to the welding-spot portion 44 near the lower edge of the lower back panel 16 due to the displacement of the projection portion 50 provided at the position including a part of the lower edge of the lower back panel 16 . As a result, it is possible to further restrain the stress applied to the welding-spot portion 44 between the lower back panel 16 and the rear floor pan 14 at the time when a load is input from the towing hitch member 54 .
- the projection portion 50 is formed generally in a trapezoidal shape of which the width increases as it goes toward the lower side in the vehicle up-down direction in a rear view of the vehicle, and the lower end of the projection portion 50 is formed to include the region which is lower than the joining portion 46 between the lower back panel 16 and the rear side member 18 in the vehicle up-down direction. That is, the upper end of the projection portion 50 is placed between the welding-spot portion 44 of the inclined wall portion 42 and the joining portion 46 to which the rear side member 18 is joined in the lower back panel 16 and the lower end of the projection portion 50 is formed to include the region which is lower than the joining portion 46 to which the rear side member 18 is joined in the vehicle up-down direction, thereby making it possible to increase a region where the projection portion 50 is formed.
- a range where the projection portion 50 is displaced, by the tensile force T applied thereto, toward the opposite side of the projecting direction, that is, toward the opposite side from the offset direction can be made large, thereby making it possible to reduce the stress toward the offset direction to be applied to the welding-spot portion 44 in the lower back panel 16 over a wide range.
- the rear end of the floor pan bottom wall portion 34 in the rear floor pan 14 is offset rearward in the vehicle front-rear direction from the rear end of the general portion 32 in the rear floor pan 14 so that the flange of the rear end does not break at the time of deep draw forming.
- the present disclosure is not limited to this, and the rear end of the floor pan bottom wall portion 34 may be offset forward in the vehicle front-rear direction.
- the offset portion 40 and the projection portion 50 in the lower back panel 16 have such a configuration that they are offset (projected) forward in the vehicle front-rear direction so as to correspond to the rear end of the floor pan bottom wall portion 34 .
- the projection portion 50 is formed generally in a trapezoidal shape in a rear view of the vehicle.
- the present disclosure is not limited to this, and the projection portion 50 may be formed in other shapes such as a rectangular shape.
- the projection portion 50 is provided at the position including a part of the lower edge of the lower back panel 16 .
- the present disclosure is not limited to this, and the projection portion 50 may be provided at a position that does not include a part of the lower edge of the lower back panel 16 .
- the welding-spot portion 44 is provided in a part of the inclined wall portion 42 near the general surface 38 (a part of the inclined wall portion 42 which part is placed outwardly in the vehicle width direction compared with the center of the inclined wall portion 42 in the vehicle width direction).
- the present disclosure is not limited to this.
- the welding-spot portion 44 may be provided in other parts in the inclined wall portion 42 .
